To determine the effectiveness of endoscopic cricopharyngeal myotomy on upper oesophageal sphincter dysfunction in adults with upper oesophageal sphincter dysfunction and neurological disease. Published and unpublished studies with a quasi-experimental design investigating endoscopic cricopharyngeal myotomy effects on upper oesophageal sphincter dysfunction in humans were considered eligible. Electronic databases, grey literature and reference lists of included studies were systematically searched. Data were extracted by two independent reviewers. Methodological quality was assessed independently using the PEDro scale and MINORS tool. Of 2938 records identified, 2 studies were eligible. Risk of bias assessment indicated areas of methodological concern in the literature. Statistical analysis was not possible because of the limited number of eligible studies. No determinations could be made regarding endoscopic cricopharyngeal myotomy effectiveness in the cohort of interest. Reliable and valid evidence on the following is required to support increasing clinical usage of endoscopic cricopharyngeal myotomy: optimal candidacy selection; standardised post-operative management protocol; complications; and endoscopic cricopharyngeal myotomy effects on aspiration of food and laryngeal penetration, mean upper oesophageal sphincter resting pressure and quality of life.
